Once upon a time, there lived a very skinny pig. The other animals in the barn laughed at(嘲笑)him, "You don't look like a pig! Other pigs are all fat, but you're so skinny! Are you a pig?" The skinny pig was sad and lonely. No one wanted to play with him because he looked different. One night, the skinny pig saw smoke coming out of the roof(屋顶)of the hen house. He heard the hens shouting, ‘Help! Help!' The other animals couldn't get into the hen house because they were so fat. The skinny pig ran inside and pulled the hens out of the fire. From that day on, the animals became friends with their hero(英雄), the skinny pig.
